Recently, the Binhai County Emergency Management Bureau of Yancheng City organized a special training on safety knowledge for hazardous chemical use in industrial and commercial enterprises. A total of 90 safety managers from industrial and commercial enterprises using hazardous chemicals at Grade A, B and C levels across the county participated.Provincial emergency management experts delivered lectures on key links including procurement, storage, collection and use, operation, and waste disposal. The signal sent by the training is clear: the safety of hazardous chemical use in industrial and commercial enterprises must be comprehensively consolidated from systems to on-site practices, and from personnel to equipment. And storage is the first checkpoint for the implementation of the "Six Musts".I. Training Sets the Tone: Storage Link Is Key to the Implementation of the "Six Musts"The training requires all regulatory authorities to focus on key links such as storage and use, and all enterprises to strictly fulfill their main responsibilities. Among the "Six Musts" for hazardous chemical use, multiple requirements such as safety labels, registration systems, warning signs, standardized storage, and storage of remaining chemicals all directly point to storage management.In reality, many industrial and commercial enterprises face difficulties such as tight site space, long approval cycles and high construction costs, making it difficult to quickly build dedicated warehouses. This leads to recurring hidden dangers such as over-storage, mixed storage, and nowhere to place remaining hazardous chemicals. To truly translate training outcomes into governance effectiveness, enterprises need a set of compliant, intelligent and rapidly deployable storage equipment.II. Against the "Six Musts": Enterprise Storage Pain Points Urgently Need Hardware SolutionsThe "Six Musts" specify that: procurement must be from qualified units; safety data sheets and safety labels must be obtained; registration systems for purchase, warehousing and outbound delivery, use and destruction must be implemented; warning signs must be installed at storage and use sites; storage must be standardized, with over-storage and mixed storage beyond the scope prohibited; and unused hazardous chemicals on the day must be properly stored in dedicated warehouses.These requirements may seem basic, but their implementation requires hardware support. Common problems include easily omitted manual ledgers, difficulty in isolating mixed storage risks, random placement of remaining hazardous chemicals, and perfunctory warning signs. DeSUN ECOTECH hazardous chemical storage cabinets are precisely designed to address these pain points, providing a tangible carrier for the implementation of regulatory requirements.III. DeSUN ECOTECH Solution: Translating the "Six Musts" into In-Cabinet CapabilitiesShanghai DeSUN ECOTECH CO., Ltd. specializes in the safe storage of hazardous chemicals, with complete certificates and authoritative certifications such as explosion-proof flame detector certificates and explosion relief window test reports.

Technical Foundation: Triad of Explosion Protection, Fire Protection and Intelligent MonitoringSafety protection is the core of DeSUN ECOTECH storage cabinets. The products are equipped with high-precision sensors to monitor indicators such as temperature, humidity and combustible gas concentration around the clock. When thresholds are exceeded, audible and visual alarms are triggered and mobile phone warning notifications are pushed. The cabinet has a built-in high-efficiency adsorption module to purify volatile toxic gases; the bottom anti-leakage design properly collects accidentally leaked chemicals, balancing safety and environmental protection.DeSUN ECOTECH also participated in the formulation of the group standard Safety Technical Requirements for Hazardous Chemical Storage Cabinets as a key drafting unit, demonstrating its technology-leading capability. For enterprises, this is not just a cabinet, but a set of monitorable, early-warning and traceable micro-warehouse safety systems.V. Scenario Verification: Benchmark Cases Across Multiple Industries Confirm ReliabilityDeSUN ECOTECH storage cabinets have been applied in scenarios such as aerospace, electric power, universities, and industry and commerce. A research institute under China Aerospace Science and Technology Corporation has adopted 6-meter temporary storage cabinets, divided into two independent spaces for storing hazardous chemicals and hazardous waste respectively, equipped with independent management systems. A vocational college in Jiangsu uses explosion-proof container-type hazardous chemical storage cabinets, equipped with systems such as explosion-proof HVAC, explosion-proof lighting, explosion-proof alarms, ventilation, monitoring and automatic fire extinguishing, which have passed the acceptance of local work safety and environmental protection authorities. These cases demonstrate that DeSUN ECOTECH storage cabinets can adapt to the storage needs of different industries, different sites and different hazardous chemicals.VI. Conclusion: Translation of Training Outcomes Requires Reliable Equipment SupportThe core of this training by Binhai County Emergency Management Bureau is to promote enterprises to implement safety management systems in practice. From training to systems, from systems to equipment, and from equipment to operational practices, every step requires solid implementation.DeSUN ECOTECH hazardous chemical storage cabinets translate complex hazardous chemical safety management requirements into visible, tangible and user-friendly hardware infrastructure. For industrial and commercial enterprises, choosing compliant, intelligent and reliable hazardous chemical storage equipment is not only a practical need to respond to regulatory inspections, but also a long-term strategy to uphold the bottom line of work safety.

Temporary storage of hazardous waste is a key focus area in environmental protection inspections. Many enterprises only attach importance to end-of-pipe disposal but take temporary storage lightly. Problems such as leakage, mixed storage and missing ledgers, once identified, will result in rectification requirements at best and penalties at worst. According to industry reports, the annual output of industrial hazardous waste in China reaches approximately 420 million tons. Environmental cases caused by non-compliant storage account for 31.7% of all hazardous waste-related cases. This figure reminds enterprises that selecting the right temporary storage cabinet is only the first step. Without sound daily management, compliance inspections will still be hard to pass.1. Risks in the Temporary Storage Link Are More Concentrated Than ImaginedWaste-generating enterprises tend to prioritize waste transit over temporary storage. Daily waste comes in diverse categories with widely different chemical properties. Random piling in the same area can easily trigger chemical reactions. Self-built hazardous waste rooms often suffer from many problems: damaged anti-seepage layers, insufficient ventilation and incomplete ledgers. Poorly planned temporary storage zones with overstacked materials, and emergency supplies placed too far away for rapid response in case of leakage, are also common issues. Small and medium-sized factories often lack forward planning and rush to make renovations only when environmental inspections are approaching. These problems are not isolated cases; they are becoming a major source of penalties.2. Hardware Compliance Is the Bottom Line; Storage Cabinets Must Meet StandardsTraditional hazardous waste rooms involve long approval cycles and high investment. Hazardous waste temporary storage cabinets, which are movable and customizable, are more suitable for small and medium-sized waste-generating enterprises. Three core indicators must be considered when selecting cabinets:- Seepage prevention: The cabinet bottom shall be equipped with an integrally molded leak-proof tray with a volume of no less than 110% of the capacity of the largest single container.- Ventilation: Forced ventilation shall be provided at a rate of no less than 6 air changes per hour, and the combustible gas alarm shall be interlocked with the exhaust system.- Material: The cabinet shall adopt double-layer cold-rolled steel plates filled with fireproof rock wool, with a fire resistance rating of no less than 1 hour.3. Installing Cabinets Without Proper Management Is a Waste of EffortCommon on-site problems lie not in hardware, but in process and detail control. Missing zone identification, insufficient employee awareness, vague requirements for incompatible waste isolation, and perfunctory daily inspections are widespread issues. Management should focus on three key points:- Classified and zoned storage: In principle, each cabinet shall hold only one category of hazardous waste; acids and alkalis shall not be mixed, and oxidizers shall be isolated from reducing agents.- Closed-loop ledger management: Full-process records of warehousing, storage and outbound delivery shall be kept for no less than five years.- Personnel training: Employees shall be clear about which wastes cannot be stored together, where emergency supplies are located, and the first steps to take in the event of leakage.Only when hardware and management advance in tandem can risks be reduced.4. Intelligent Temporary Storage Cabinets Replace Manual Control with Systemic ManagementManual ledgers are prone to omissions and loss, and on-site inspections cannot achieve round-the-clock coverage. Intelligent hazardous waste temporary storage cabinets are changing the situation. They support swipe-card access for waste deposition, automatic weighing, real-time data upload and automatic generation of digital ledgers. When the hazardous waste inventory in the cabinet reaches the upper limit, the platform automatically pushes a collection and transportation work order. Temperature, humidity, VOCs and combustible gases are monitored by sensors. Abnormal conditions trigger automatic alarms, which are interlocked with the exhaust system. The system supports remote access, allowing managers to check the status via mobile phones. This mechanism turns the slogan of traceable sources, trackable destinations and accountable responsibilities into a data-driven chain.5. Installation Alone Is Not Enough; Daily Operation and Maintenance Determine Long-Term ComplianceHazardous waste storage management is a long-term task, not a one-time project. Cabinets shall be inspected weekly for corrosion, welds and door seals. Leak-proof trays shall be checked daily for accumulated liquid, and collection drums must not overflow. Ventilation openings and sensors shall be cleaned and calibrated regularly, and alarm functions shall be operational at all times.Enterprises cannot stop at construction and delivery; subsequent operation and maintenance also require continuous implementation. They shall customize temporary storage cabinet solutions based on their own waste types and generation volume, and support them with corresponding inspection management specifications. By putting daily control in place in advance, enterprises can reduce environmental risks, respond smoothly to environmental supervision, and avoid unnecessary economic losses.6. Common Deduction Points in InspectionsThere are many common deduction points during inspections: unlocked cabinets accessible to unauthorized personnel; incomplete label information with only "waste liquid" marked — labels shall include name, category, code and hazard characteristics; unclear compatibility grouping with acids and alkalis stored in the same cabinet; accumulated liquid in leak-proof trays not cleaned in time; blocked ventilation openings and malfunctioning alarms; discrepancies between ledgers and actual inventory with missing dates or quantities; expired emergency supplies and insufficient absorbent cotton. These details may seem minor, but they directly affect inspection results.7. Emergency Material Configuration Determines Response Speed After LeakageAbsorbent cotton, oil-absorbent felts and sandbags shall be placed beside temporary storage cabinets, along with chemical protective gloves, goggles and fire extinguishers. Leakage emergency drums shall be placed close to the cabinets and kept unlocked. Signs shall be clear and employees shall be trained to use the equipment. Leakage drills shall be conducted quarterly, with records of drill time, participants and corrective actions. Emergency response capability is not a formality; it is the last line of defense.8. Proactive Planning Ensures Calm Response to InspectionsMany enterprises mistakenly believe that purchasing cabinets guarantees compliance, but compliance is an ongoing process. Identification, ledgers, training and inspections are all indispensable. Temporary storage cabinets are not all-purpose solutions; they require institutional support and personnel execution.The earlier enterprises sort out their waste generation lists, define zoning plans and establish inspection mechanisms, the better. The more detailed daily management is, the calmer inspections will be. The lower the environmental risks, the more stable production will be.Temporary storage of hazardous waste is not a one-time project. Choosing the right cabinet is the first step, but sound daily management is the key. With proactive planning and continuous control, enterprises can face environmental inspections calmly, pass inspections smoothly, and reduce losses from on-site rectification and production shutdowns.

Recently, two sets of intelligent battery storage cabinets from DeSUN ECOTECH have been successfully delivered from the domestic factory to the customer’s site in Germany, completing a one-stop delivery process covering scheme design, manufacturing, export certification, international logistics and on-site deployment. This is not merely a product export, but also a concentrated demonstration of DeSUN ECOTECH’s technical capabilities, compliance competence and engineering service capabilities in the field of battery safety storage. Facing the strict safety and environmental access requirements of the German and EU markets, the product has successfully entered European industrial application scenarios by virtue of its professional multi-layer protection design, intelligent monitoring system and complete international certifications. Focusing on Full-Scenario Battery Storage to Reshape Safety Management Standards With the rapid development of new energy vehicles, energy storage systems and the consumer electronics industry, the demand for temporary storage of batteries in different states — finished, waste and pending testing — continues to rise. Safety risks in the battery storage link are characterized by high concealment, rapid chain reactions and severe secondary hazards. Once thermal runaway, short circuits, electrolyte leakage or harmful gas release occur, they can easily trigger fires, explosions and environmental pollution accidents. DeSUN ECOTECH’s intelligent battery storage cabinets are specially developed for temporary storage scenarios throughout the entire battery life cycle. Designed in accordance with relevant standards such as the Management Specification for Recycling of Traction Batteries for Vehicles – Part 2: Recycling Service Outlets (GB/T 38698.2-2023), the products focus on fire protection, explosion protection, short circuit prevention, thermal runaway prevention and all-round monitoring, and are applicable to multiple links including battery production, recycling, testing, operation and maintenance turnover. The company’s "intelligent and digital retired battery storage equipment" was selected into the 2025 Catalogue of Practical Technologies and Typical Projects for Ecological Environmental Protection, gaining national-level recognition and fully reflecting its professional accumulation in the fields of environmental protection and safety. Seven-Layer Safety Protection to Build an Active Defense System From structural design to functional configuration, these battery storage cabinets are developed around the actual risks of battery storage, forming a multi-layer safety protection system. In terms of fire and explosion protection, the cabinet body adopts high-strength explosion-proof steel with a three-layer fireproof structure, endowing the entire cabinet with explosion-proof capability. The cabinet is equipped with pressure relief explosion-proof valves or pressure relief devices. When the internal pressure rises sharply due to battery thermal runaway, they can release pressure directionally, effectively reducing the risks of cabinet rupture and secondary combustion and explosion. In terms of short circuit prevention, an insulating isolation layer is installed inside the cabinet to physically avoid abnormal contact between battery positive and negative electrodes and reduce fire hazards caused by short circuits. Meanwhile, the cabinet supports zoned isolated storage, where batteries of different specifications, states of charge and safety levels can be stored separately. This not only facilitates refined management, but also avoids cross risks caused by mixed storage. For temperature-sensitive batteries, the cabinet is equipped with an intelligent constant temperature control system that can be accurately adjusted within the range of -10℃ to 60℃. It adapts to the differentiated storage temperature requirements of different types of batteries, and reduces the risks of accelerated battery aging due to excessive temperature or performance degradation due to low temperature. In terms of leakage prevention and environmental treatment, an anti-leakage tray is designed at the bottom of the cabinet. In the event of battery electrolyte leakage, it can effectively contain the liquid and prevent corrosive liquid from overflowing and contaminating the ground and environment. To address the problem that harmful gases such as fluorides are easily generated from the leakage of battery anode materials, the product is specially equipped with waste gas purification facilities, which adopt chemical materials for neutralization and filtration treatment to ensure that waste gas meets emission standards, balancing storage safety and environmental protection. In addition, the product supports the configuration of auxiliary function modules such as charging and discharging, which can meet the practical needs of battery charging and maintenance for batteries pending testing, further improving the applicability of the product in testing and operation scenarios. Intelligent Digital Management for Visible and Controllable Risks Different from traditional storage cabinets, DeSUN ECOTECH’s intelligent battery storage cabinets emphasize "active monitoring, intelligent early warning and data traceability". The product is equipped with an all-round monitoring system that can collect key parameters such as internal temperature, smoke and combustible gas in real time. When abnormal monitoring data occurs, the system can send early warning signals in time to gain disposal time for on-site personnel, and can link safety measures such as ventilation and power off according to preset logic to reduce the risk of accident escalation. The digital management platform can record storage environment data, alarm information and operation status, helping enterprises achieve refined management and safety traceability in the battery storage link. This mode of "hardware protection + software monitoring" upgrades temporary battery storage from passive protection to active risk management, which is more in line with the requirements of modern enterprises for work safety and digital operation. Complete Certifications for Smooth Entry into the German Market As a product exported to Germany, compliance is a key link that cannot be ignored. DeSUN ECOTECH’s intelligent battery storage cabinets have obtained relevant export certificates such as CE certification and ATEX international explosion-proof certification, meeting the requirements of EU directives and standards in terms of mechanical safety, electromagnetic compatibility and explosion protection. The German market has extremely high safety and environmental thresholds for industrial equipment. The smooth certification and delivery of the product to the customer’s site fully demonstrates that its design, manufacturing and performance have reached the international advanced level. The two sets of cabinets exported this time were fully delivered by DeSUN ECOTECH in a one-stop manner, from factory production to on-site deployment at the German customer’s site. The company completed relevant certifications and tests in advance, adopted a packaging protection scheme suitable for sea transportation and long-distance transit, and followed up the whole process of international logistics, customs clearance and on-site delivery, ensuring that the products can be quickly installed and put into use after arriving in Germany. This one-stop delivery capability reduces customers’ burdens in cross-border procurement, compliance review and engineering coordination, and also lays a solid foundation for subsequent expansion of the European market.

The exported standard solid containers and standard liquid containers retain standardized modules such as EU-standard pallet bases, stackability and forklift compatibility, but are customized in specific dimensions, interfaces, sealing structures and lifting positions according to the client’s actual operational needs.Starting from early demand research and material property analysis, the technical team carried out adaptive design for the containers in combination with local loading and unloading conditions and transportation practices in Kazakhstan. This design not only ensures safe turnover of specific materials, but also enables seamless integration with the client’s existing logistics and storage systems. During production, DeSUN ECOTECH strictly controls key processes including blanking, welding, hot-dip galvanizing, lining installation and leakage testing, to ensure that every container meets export standards in terms of strength, corrosion resistance, sealing performance and dimensional accuracy.1. Standard Liquid Containers: Leak-Proof, Corrosion-Resistant and StackableStandard liquid containers are one of the key products in this delivery. Positioned with core advantages of "standardized design, corrosion resistance, full sealing and intelligent IoT connectivity", they are specially built for temporary turnover and transit of liquid hazardous waste and hazardous chemicals.Made of carbon steel or stainless steel with hot-dip galvanized surface treatment and PP lining film, the containers are compatible with various liquid hazardous waste and chemicals such as acids, alkalis and organic solvents. The integrated sealing design, paired with large-diameter top lids, leak-proof sealing gaskets and anti-theft lock catches, effectively prevents liquid leakage and volatilization pollution, and reduces environmental risks during transportation and storage.Lifting lugs are installed at the bottom, and fixing slots are designed to prevent the containers from tipping over during transit. The EU-standard pallet base design supports stacked storage, improving space utilization by 50% and facilitating forklift and pallet transfer. A labeling area is reserved on the container surface for on-site personnel to mark material type, batch, weight and other information, enhancing the standardization and traceability of hazardous waste management.Standard liquid containers provide stable and reliable safety guarantees in scenarios such as liquid material turnover zones in chemical plants, liquid hazardous waste transit in hazardous waste treatment centers, liquid reagent turnover in laboratories, and liquid material transportation in the logistics industry.2. Standard Solid Containers: High-Strength, Fully Sealed and LabelableStandard solid containers focus on core functions of "sturdiness and durability, fully sealed dust protection, stackability and classified labeling". Made of thickened cold-rolled steel plates or stainless steel and treated with hot-dip galvanizing on the surface, they feature excellent impact resistance and wear resistance, and can meet the handling and stacking needs of various solid materials such as iron filings, batteries, sludge and animal carcasses.With an additional plastic lining, they can also adapt to highly corrosive substances, further expanding the application scope. The sealed cover plate design prevents dust escape and external contamination. Lifting lugs are arranged on the top of the box body to support stacking and reduce space occupation. Label holders are equipped on the container surface to support full-process identification of material type, batch and classification, helping enterprises achieve refined management in solid waste classification, storage and transit links.Whether in solid hazardous waste turnover zones in industrial parks, general industrial solid waste transit in manufacturing factories, solid sample turnover in laboratories, or centralized collection of solid materials in the recycling industry, standard solid containers can significantly improve turnover efficiency and space utilization.3. Export Packaging: Multi-Layer Protection for Cross-Border DeliveryIn cross-border delivery, packaging quality directly determines whether products can arrive at the client’s site safely. All products in this batch are packed in export wooden cases, principally fumigation-free plywood wooden cases that comply with international phytosanitary requirements for wooden packaging, avoiding delays in customs clearance caused by fumigation issues.Meanwhile, according to the structural characteristics of the products, DeSUN ECOTECH has equipped base supports, corner protectors, moisture-proof films, cushioning materials and internal strapping and fixing devices. The base supports and corner protectors enhance the overall strength of the cases and prevent local deformation during stacking and lifting. The moisture-proof film reduces the impact of humidity changes on metal containers during long-distance transportation. The cushioning materials and internal strapping and fixing devices effectively suppress displacement and collision caused by transportation bumps.This multi-layer protection system of "support – moisture proof – cushioning – fixation" not only protects the products, but also reflects DeSUN ECOTECH’s attention to detail in export delivery.4. Intelligent IoT Connectivity and Standardized Design: Boosting International Turnover EfficiencyIn addition, both standard solid containers and standard liquid containers can be optionally equipped with intelligent IoT functions such as positioning modules, smart locks and data transmission, realizing digital tracking and remote control throughout the turnover process.For cross-border projects like the one in Kazakhstan, clients can monitor the real-time location, opening/closing status and transit nodes of containers via the platform. This reduces management blind spots in the turnover of hazardous waste and chemicals, and improves safety and compliance levels. The standardized EU-standard pallet base design gives the products higher compatibility in the logistics systems of Central Asia and broader markets, reducing transit losses and efficiency losses caused by specification differences.5.

In the chemical, pharmaceutical, scientific research and industrial manufacturing sectors, the safe storage of flammable liquids has always been a top priority in enterprise safety management. An accidental fire can not only cause huge property losses, but also endanger personal safety and damage the ecological environment. How to ensure that safety storage cabinets for flammable liquids can hold their ground under extreme fire conditions and buy precious time for personnel evacuation and fire fighting is not only a mandatory regulatory requirement, but also a core concern of every responsible enterprise. Recently, the industrial-series flammable liquid safety storage cabinet (Model: DeSUN-FRC-TYP90) independently developed by Shanghai DeSUN ECOTECH CO., Ltd. (hereinafter referred to as "DeSUN ECOTECH") has successfully passed the strict fire resistance test conducted by SGS, the world’s authoritative testing and certification body. The test was carried out in accordance with the latest EU standard EN 14470-1:2023, and the product was finally awarded the highest fire resistance rating under this standard: Type 90 (90-minute type). This milestone achievement marks that DeSUN ECOTECH’s technical strength in the field of hazardous chemical safety storage has reached the international leading level, and sets a new benchmark for the quality of domestic flammable liquid safety storage cabinets. Authoritative Verification: Rigorous SGS Test Demonstrates Solid Technical Strength with Hard Data SGS is the world’s leading inspection, verification, testing and certification body, whose test reports are recognized by numerous authoritative institutions worldwide. This test was strictly implemented in accordance with the 2023 revised EU standard EN 14470-1 and conducted on June 16, 2026. During the test, the safety cabinet was placed in a test furnace simulating a real fire and heated continuously for 90 minutes following the standard time-temperature curve specified in EN 1363-1:2020. The average temperature inside the furnace was precisely controlled to strictly fit the standard curve, ensuring the authenticity and authority of the simulated environment. Under such harsh conditions, the performance of DeSUN ECOTECH’s flammable liquid safety storage cabinet was impressive. The standard requires that the temperature rise at any measuring point inside the cabinet shall not exceed 180 K (Kelvin). After 90 minutes of exposure to intense fire, the maximum temperature rise inside the cabinet was only 146.5 K. Calculated based on the ambient temperature of 26℃ at the start of the test, the maximum internal temperature of the cabinet was approximately 172.5℃, far below the upper limit of about 206℃ allowed by the standard, with sufficient temperature rise margin and excellent thermal insulation performance. Post-test inspection showed that although the cabinet body turned grayish white and the cabinet door was slightly deformed, there was no obvious abnormality inside except for minor discoloration. The cabinet door did not burst open and retained its locking function, with the overall structural integrity well maintained. This means that even in an extreme fire environment with an external temperature exceeding 900℃, the storage cabinet can still keep the internal temperature within a safe range and provide up to 90 minutes of effective protection for flammable liquids. Technology-Driven Excellence: Meticulous Design Builds a Reliable Safety Barrier Behind this outstanding result is DeSUN ECOTECH’s unremitting pursuit of technological innovation. Founded in 2018 as a national high-tech enterprise, DeSUN ECOTECH has always adhered to the mission of "realizing industrial safety through technology".

With the large-scale deployment of service robots in offline stores such as retail outlets, supermarkets and catering establishments, the daily indoor charging of robot lithium batteries has emerged as a highly overlooked safety risk in store operations. Featuring open spaces, dense pedestrian flow, abundant surrounding combustibles and a general lack of professional lithium battery safety operation and maintenance capabilities, traditional open charging modes are fraught with hidden dangers.To address this issue, a Shanghai-based intelligent technology company has introduced customized lithium battery charging protection cabinets from DeSUN ECOTECH. Tailored to the actual scenarios of stores, the solution targeted resolves multiple charging pain points. The following elaborates on the pain points and corresponding solutions respectively.Five Core Pain Points and Hidden Risks of Indoor Battery Charging in Stores1. Limited space with heavily overlapping charging and operational areasConstrained by floor space, charging areas in stores usually intermingle with product displays and pedestrian routes, lacking independent safety isolation spaces. Once thermal runaway occurs in lithium batteries due to overcharging or internal short circuits, open flames and high temperatures will quickly spread to surrounding goods and personnel, easily causing property losses and safety accidents.2. Concentrated battery placement triggers chain reactions from thermal runawayUnder the traditional charging mode, multiple batteries are charged in a concentrated area. When thermal runaway occurs in a single battery, it will rapidly ignite adjacent batteries and trigger a catastrophic chain reaction, exponentially increasing the difficulty of fire extinguishment.3. Insufficient professional competence of frontline staff with limited emergency response experienceFrontline store staff generally lack professional knowledge of lithium battery safety, with inadequate ability to identify early warning signs such as battery swelling and abnormal heating, as well as scarce emergency response experience, which often leads to missed optimal intervention opportunities.4. Unattended overnight charging allows minor hazards to escalate into major accidentsMany stores choose to charge batteries after closing at night, with the entire process left completely unattended. Fires cannot be detected and extinguished at the earliest moment, and even minor hidden dangers may escalate into severe accidents without intervention.5. Tightening safety supervision exposes non-compliant charging to regulatory risksCurrently, safety supervision over lithium battery charging in business premises is becoming increasingly strict across regions. Non-compliant charging practices face practical pressures such as rectification requirements and penalties, adding to the operational burden of stores.DeSUN ECOTECH Charging Protection Cabinets: Five-Layer Protection with Targeted SolutionsFirst Layer: Double-layer fireproof sealed cabinet structure blocks external fire spreadTargeting the pain points of compact charging spaces and abundant surrounding combustibles in stores, the charging cabinet adopts a fully sealed structure of double-layer steel plates with fire insulation layers, paired with flame-retardant sealing strips to achieve complete airtightness of the compartment. The entire cabinet has passed national explosion-proof certification and authoritative fire performance testing. Even in the event of extreme thermal runaway of batteries inside the compartment, flames and high temperatures can be firmly contained within the cabinet, providing reliable protection for surrounding personnel and goods.Meanwhile, the cabinet is optimized specifically for indoor scenarios. It does not require extra large floor space and can be flexibly placed in store storage rooms, back offices and other areas. Without disrupting normal operational flow, it creates an independent safety protection space for battery charging.Second Layer: Independent physically isolated compartments prevent thermal runaway chain reactionsTo address the chain reaction risk of concentrated charging of multiple batteries, the charging cabinet features a design with multiple independent compartments, with strict physical isolation between each compartment. Each battery is charged separately in an independent compartment, structurally blocking the spread path of thermal runaway from a single battery to others, and greatly reducing the probability of chain combustion and explosion.Each independent compartment is equipped with dedicated temperature and smoke detection devices as well as fire suppression components, which can accurately identify abnormal conditions in a single compartment and activate targeted protection. Protection triggered in one compartment will not affect the normal charging of others, ensuring safety while minimizing the impact of abnormal conditions on overall charging scheduling.Third Layer: Full-chain electrical protection and simplified operation for most O&M scenariosTo eliminate electrical safety risks during charging, the cabinets are equipped with a full set of professional power distribution systems, integrating multiple electrical protection mechanisms such as leakage protection, overload protection and short circuit protection. It avoids safety problems caused by circuit faults from the charging source, and fully complies with power consumption specifications for indoor commercial scenarios.Easy-to-understand emergency stop buttons and status indicators are installed on the front of the cabinet, with an external high-decibel audible and visual alarm. When abnormalities occur, it automatically triggers audible and visual warnings. With simple and intuitive operation logic, ordinary store staff can quickly complete emergency power-off operations.
